I TOOL.

Application filed January My invention relates to tools,and is hereinaft-er described as applied more particularly to a wrench having a plurality of bars each provided ,with nut-engaging portions, -al.

though such portions maybe modified to serve In 'various'types of multip'art wrenches having fixednut-engagingjaws,f as fheretotoreconstructed, difliculty has been experienced in providing, within. acompact space,- a sufiicient number of nut-engagingmembers,

and difficulty has also been experienced in providing a structure wherein -su'1ficient strength and leverage is provided. 1 Also,;-

some of such wrenches are notconveniently operable to turn" a nut inzbothdirections, and others are of 'suchfornrt'hat they can not-be brought into proper radial a nut to be'operated-upom;

My invention has for its object the-provision of an improved form of wrench "wherein the "foregoing Objections are either partially lineinent with a or entirely eliminated, and to'simplify and improve the structure and arrangement combination tools generally. v

Some of the forms which my invention may take are shown in the accompanying drawing, wherein Figure 1 is a plan view of a tool embodying my invention 2 is an inverted plan view of the structure of Fig. 1; Fig. 3 is a view, taken on the line IIIIII Fig. 1; 4 is a cross sectional view, similar to that of Fig. 3, but showing a modified form of tool; Fig. 5 is a plan view of still another modification embodying my invention; Fig. 6 is a view taken on the line VIVI of Fig. 5; Fig. 7 is a plan view of still another form of tool, and Fig, 8 is a view taken on the line VIIIVIII of Fig. 7.

Referring'now to Figs. 1, 2 and 3, I show a wrench structure having'a, body portion 10 whose ends are recessed at 11 and 12, for engaging nuts of larger sizes. The body portion is provided with pairs of flanges 13 and 14, whose free edges are turned in slightly as indicated more clearly in Fig. 3, to engage the edges of slide bars 15 and 16, which edges are beveled or of approximately dove-tail form.

The bars 15 and 16 are provided with slots 7, 1927." Serial No; 159,546.

- Theibar15 is provided witlrnut-engaging recesses at-.its ends while the'bar 16 is shown; as having anut-engagingrecess on one 'end, and as. having its other end, in the form'of a screw driver. having thumbengaging recesses 18,-by means [of which it can be nore readily slid back and forth, since theoperator can hold a tool in one hand andwiththe thumb ofthathand manipulate the slide: bar- The bar--16 can, ofcourse, be provided with similarrecesses.v

It will; be apparent that for nuts-in. the larger sizes, thelslides 15 and 16 willbe per- .mitted to remain in the retracted position shown in full lines in Figs. 1 and 2, and the ends ll'and 12 of the main bar utilized-to turn 1 such nuts. The wrench will probablylbe made i ,of convenient pocket size, and if greater leverage is required than that possible with the limited length ofthe bar 10, one of the slides 15- 16 may be-projectedin a direction away from the nut and utilized as a lever.

For nuts of the next, smaller size, the bar 15 may be slid to the position indicated by dotted [lines in Fig. 1,,while for still another smaller size, itwill be correspondingly slid in the 'opposite direction. @The; bar 16 isalso slid-J able in either direction t0 bFlDgitSl1lltel14 gaging end or its screwdriver portioninto operative position. 7

In Fig. 4, I show an arrangement similar to that of Figs. 1 to 3, but wherein additional slides are provided, in order to furnish a greater number of tools. lVhereas, in Figs. 1 and 2, six tools'are provided, two on each of the three bars, in Fig; 4 I provide five bars. The main bar 20 corresponds to the bar .10 of Figs. 1 to 3 and is provided with pairs of flanges 21 and 22 that are grooved for the reception of slides 23, 24', 25 and 26, which slides correspond to the slides 15 and 16. The

' edges of the slides 23 to 26 are supported in the grooves of the flanges 21-22 and the slides have longitudinal slots through which apin. 27 extends to limit their sliding move-' ments. The pin 27 is shown as having a drive fit with a hole in the main bar 20. As in the case of theslides 15 and 16, the slides. 23 to 26 are selectively operable to bring their ends into operative position.

Referring now to Figs. 5 and 6, I show a main bar 30 that corresponds to the bar 10 of Fig. 1., but whose flanges 31 and 32 are not bent inward as are the flanges 13 and 14 of Fig. 3. In the device of Fig. 6, slides 33 In Fi 's. 7 and 8 the main bar 36 has aairs,

o1. flanges 37 and 38 between which bars 39 and 10, that correspond to the bars and 1(3, are slidably supported. Portions of the flanges. 37 and 38 are peened inwardly as indicated. at 41, to partially overlie the slides 39 and 40 and prevent such slides from falling out of place. Longitudinal movement of the slides 39 and 40 is limited by a pin 42 that extends through the bar 36.

From the foregoing it will be seen that I providea multipart wrench of simple and compact form, whose various parts have toolengaging portions-at each end, so that for a given thickness of structure, I am enabled to provide for operation of a maximum number of sizes of nuts. It the slides were each provided with a nut-engaging member on only one of its ends, it will be seen that a structure of twice the thickness would be re.- quired, with the result that for some nut sizes, the wrench could not be brought into proper radial alinement with the nut, but that the wrench would lie at a too greatly inclined position to properly engage such nuts. It will also be seen that considerable leverage over that permissible with the length of the main bar ispossible through extension of one of the slides, or that for nuts of smaller sizes, one of the slidescan be projected in one direction to-engage the nut. and the other slide projected in the other direction to provide the desired leverage,

I claim as my invention 1. A tool comprising a bar having'anutengaging recess in each end and serving as a grip member, the bar having a longitudinally-extending exposed channel in one side, and a second bar slidably supported in said channel and having a nut-engaging recess on each end, the second bar being of shorter length than-the distance between the firstnamed recesses. but movable to such positions that each of its ends will project beyond the adjacent ends of the first-named bar, and each of said nut-engaging recesses being complete in itself for the turning of a nut.

2. A tool comprising a bar having a lon--- gitudlnally-extending exposed channel, and

a second bar slidably supported insaid channel and having tool members formed on its" ends, the second bar being of shorter length."

than the first-named bar but movable to such positions that each of its ends will project beyond the adjacent end of the first-named complete in itself.

3. A tool'comprising a bar havinga longithe first-named bar but movable to such positions that each of its ends will project beyond bar, and each of said tool members being the adjacent end of the first-named bar, and

each of said tool members being complete in itself. I V

In testimony whereof I, the saidFnnnmcn SIEVERN, have hereunto set my hand.
